It’s the age-old question — boiler or furnace? There are pros and cons to both. Furnaces last longer cost less to install, and can start heating much quicker, but lose out on some energy efficiency due to ductwork. Boilers have been preferred in New York for a long time, but aren’t as common in other parts of the country. A boiler’s pipes don’t lose as much heat as ducts, so they are more energy-efficient, especially with newer models. You’ll likely have to replace it a few years sooner than you would a furnace.
